[Android Q&A, Help & Troubleshooting] Jigen90:
Samsung Galaxy S2 I9100

CM 10.1 (02 apr 2013 build)

I installed aosp3 package 2802 & 2805

wiped dalvik, cache and fixed permissions

BeatsAudio Effect is working when I set up equalizer, bass, etc.

BUT

whenever I select Audio Effects in Audio Settings I cannot see any window, nor panel!

This is log message

Audio Engine works, I did aaengine procedure with adb emulator and it's ok (my build.prop file is complete with all tweaks).

BTW I think there are some problems with musicfx apk!

Using APK-tool on MusicFX, I get

I: Loading resource table...
I: Decoding resources...
